As shown in the previous paper1), a toxic substance having lethal toxicity to mice intraperitoneally has been proven to produce by a strain of Rettgerella-like bacteria in the octopus muscle extract medium, and the substance seemed to have a non-basic nature according to the phosphotungstic acid fractionation procedure. The basic fraction itself was not poisonous but enhanced the toxicity of the non-basic fraction. Present paper deals with the isolation and identification of the synergetic factor in the basic fraction. Results obtained may be summarized as follows: The synergetic substance was successfully isolated by the ion exchange resin technique, using an Amberlite IRA-400 (OH type) column for the lst step, and an Amberlite IRC-50 (H type) column for the 2nd step. The purified crystal was found to enhance the toxicity of the non-basic fraction (Table 1), and the phenomenon seemed to coincide with that reported in the previous paper1). This substance was identified as glycine-betaine from its Rf value on paper chromatograms (Fig. 1), and from its melting point of picrate derivative (Table 2).
